To al?, whom t may concern:

Be it known that I, VViLLLAM L. GRAN, a citizen of the United States, residing at Kingston, in the county of Itoane and State of Tennessee, have invented certain new and useful Improvements in Harrows; and I do declare the followin to be a full, clear, and exact description oig the invention, such as will enable others skilled in the art to which it apertains to make and use the saine.

y invention relates to improvements in harrows; and it consists in the construction, combination, and arrangement of' devices hereinafter described and claimed.

The object of my invention is to effect improveniente in the construction of the harrow-frame, whereby the same is adapted to be adjusted in width to any desired extent and whereby the same may be folded cornpactly to economize space in storage and when being transported.

In the accompanying drawings, Fi ure 1 is a perspective view of a harrow emi my improvements, showing two sections o my barrow combined and provided with a common draft-bar. Fig. 2 is a detail transverse sectional view taken throu h one of the harrow-frames near the front en thereof and showing the pivotal connection between the side bars of said harrow-frame Fig. 3 is a similar view taken on a plane intersecting the cross-bar which connects the side bars to the barrow-frame and the ends of which are detachably connected thereto. Fig. 4 is a perspective view of one section of my improved harrow, showin the same adjusted and narrowed, so that it may be used between rows of plants for harrowing the ground between said rows. Fi 5 is a perspective view of one section of t e hai-row, showing the same compactly folded for storage or transportation.

Each section or frame of m improved harrow comprises a air of si e bars l1 and a cross-bar 2, each o which is made of angle or channel steel or iron. The horizontal upper anges of the side bars 1 overlap at their front ends, and the said side bars are pivotally connected together at their front ends by means of a bolt 3, the upper end of which 1s formed with a forwardl -extending hook 4, which is adapted for t e attachment of a odyin draft-bar, swingletree, or the like, as will be readily understood. The horizontal upper flanges of the side bars 1 are provided at suitable points with adjustin openings 5. The upper horizontal flange o the cross-bar 2 is provided near the ends thereof with openings 6, which are adapted to register with the openings 5, and pins or bolts 7 are placed in said registering openings to secure the said cross-har to the side bars at an T suitable distance from the rear ends of t e latter, and hence the said cross-bar is enabled to secure the side bars at any desired anglo with respect to each other, so that the frame or section of the harrow may be widened or narrowed, as desired. The vertical web or flan e of the said cross-bar is provided with notdlies 2U at its ends to receive the horizontal webs of the side bars.

The vertical flanges or webs of the side barsare provided at suitable distances apart with openings for the reception of eyebolts 8, which are employed in connection with holding devices 9 to secure the barrow-teeth l0.

When the cross-bar has been removed from between the side bars of the harrowframe or section, said side bars ma be closed together and disposedI in arallel re ation, and the cross-bar may then e secured on one of the side bars of the harrow by means of the pins or bolts 7, which may be placed in the openings with which the upper side of said cross-bar and the upper sides of the side bars are rovided.

rom the fore oing description, connection with t e acoompanyin drawings, the construction and operation o the invention will be readily understood without requiring a more extended eX lanation.

Various changes in the orm, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrrlicing any oi the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A harrow comprisin side bars of angle metal havin horizonte. and depending vertical webs, t e horizontal webs of the said bars being overlapped and pivotally connected together at their front ends, a rigid taken in IOO cross-bar of angle metal, having a horizontal web to lie on those of the side bers and a vertical web provided with notches at its ends to receive the horizontal Webs of the side bars, VVILLAM Il. GRAN. and means to adjustabl secure the ends of Witnesses:

the horizontal web of the cross-har to the W. M. GALYoN.

horizontal Webs of the side bars. M. A. J. PRICE.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
